EYEGLASS- Application filedJune 6,

To all whom it may concern: a

Be it known that I, FREDERICK (J. MERRY, a citizen of the United States,residingat Kansas City, in the county-of Jackson and State of Missouri,have invented certain new and useful Improvements in Eyeglass-Mountings; and I do declare thefollowing to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to rimless eyeglass mountings and one of theobjects thereof is to provide an eye-glass mounting in which the part tobe secured to. the lens may be fastened thereto by clamping jaws adaptedto be drawn into intimate contact with the lens by a tensioning devicepassing through a hole in the lens and so constructed that thetensioning device will be invisible from the front of the lens so thatthe mounting will have the appearance of a cemented connection.

In other words, the screw or tensioning device cannot be observed fromthe front of the lens; therefore, a neat connection will be provided. I

Another feature of the invention is that the screw for the tensioningdeviceis received within the lens-supporting sleeve or stud so that thelens is supported upon the stud, permitting relative movement'betweenthe lens and the mounting to effect annular adjustment without dangerof, the screw working loose.

The stud is provided with a cap which constitutes a cover plate for oneof the jaws of the eye glass mounting, the advantage being that the lenscan be slipped between the jaws of the eye glass mounting withoutspringing them apart. Then the stud with the cover plate can beintroduced to hold the lens in place, the cap or cover late shieldingthe opening in the jaw and t e opening in the lens.

With the ordinary construction of eyeglass mountings in which a screw isused as a tensioning means for the clamping jaws, the lens is supporteddirectly upon the screw. The result is that when the lens becomesslightly loose, it will have-a slight swinging movement with respect tothe mounting,

causing the screw to turn and work loose, which is a serious defectbecause the screw not infrequently drops out and is lost.

According to my inventiomhowever, the

lens is mounted upon a fixed stud so that movement of the lens cannotimpart movement to. any element of the eye-glass mounting. Therefore, atight connection between theeye-glass mounting and the lens is insured.7 Other advantages of the invention will be apparent by reference to thefollowing descr ption in connection with the accompany 111 drawings, inwhich- *igure 1 is a perspective view of a pair of eye-glasses equippedwith a mounting constructed in accordance with my invention.

Fig. 2 is an enlarged fragmentary View of a lens and part of themounting viewed from the front of the lens.

Fig. 3 is a similar view from the rear of the lens.

Fig. 4 is a disassociated view f the mount ing and part of a lens.

Fig. 5 is a transverse sectional view through a part of the lens and oneend of the mounting, and

Fig. 6 is a similar view of a slightly modified form of the device.

The mounting is applicable to either the temple stud or to the nose orbridge piece for a rimless eyeglass mounting but I have shown in detailthe mounting as applied specifically to the nose piece or bridge. Ineither event, the part to be secured to the lens involves the samegeneral construction.

Referring now the drawings by numerals of reference:

l designates the nose piece or bridge having ends 2 and 3, each of whichis provided with diametrically opposite, segmental, lensengaging fingers4L and 5, which are adapted to lie against the perimeter of the lens 6.

Extending in parallel relation from the lens-engagin fingers at and 5are two parallel jaws 7 anc 8, which are adapted to lie on oppositesides of the lens6' and clampit between them. One of the jaws, in thepresent instance 7 is provided with an opening or hole 9 to receive ahollow internally threaded stud or sleeve 10 having a head 11co-extensive with and adapted to fit over the outer face 12 of the jaw 7and by reference to Fig. a it will be observed that the outer face 12 ofthe jaw 7 is provided with oppositely inclined portions 13 and 14 toreceive the head or coverplate 11, which is substantially V- shaped incross section so that the under faces 15 'and 16 will lie snugly againstthe face 12 in such a manner that there can be no turning movement ofthe stud because there can be no turning movement of the head or plate11. Since the head or plate 11 is co-extensive with the-jaw 7, the jawwill be completely covered by the head or plate, presenting an unbrokensmooth appearance, covering the joint and making a blind connectionsothat the mounting viewed from the front will have the appearance of acemented mounting. I

The approximate lengthof the stud 10 is equal to the space between thejaws 7 and 8; in actualpractice, it is slightlyaless than the distancebetween the jaws so that the tension screw 16 may exert tension to drawthe two jaws together, as will be clearly apparent by reference to Fig.5.

The jaw 8 is provided with a countersunk recess 17 provided with a holeor opening 18 to receive the threaded end or shank 19 of the tensionscrew 16, the head 20 being received within the recess, as will beclearly seen in Figs. 4' and 5.

- When the mounting is to be attached to i the lens, the jaws will becaused to straddle it so th'at't'he hole 21 will aline withthe openings9 and 18 of the jaws 7 and 8. Then the stud 10 will be introducedthrough the opening 9 into the opening 21. The tension screw 16 may thenbe passed through the opening 18 to engage the internally threadedportion 22 of the stud 10 and turnedbya'screw driveror suitable tool todraw the two jaws together, the plate 11 being drawn tight upon theouter face of the jaw 7 so that the finished connection will have theappearance shown-m Figs. 1 and 2. r

The'iconstruction shown in Figs. 1 to 5,

both inclusive, is for a straight lens; Where a concavo-conveX lens 13used, however, the

same construction-will prevail except that the stud 10 will be arrangedat an angle to the head or plate 11 and the jaws 7 8" will be arrangedatan angle to the end3. The temple studs 23 and 24; may be fastened tothelenses in the same manner as the nose piece or bridge, the temples 25and 26 being pivoted at their ends in the usual manner.

From the foregoing it will be apparent that a novel, efficient andeasily assembledeyeglass mounting is provided, which will present anartistic symmetrical appearance when viewed. from the front of the lensand that the means of connecting the lens to the mounting will bemvisible due to the novel construction of the tensioning device, whichis provided with the head or cap plate to cover the outer jaw of themounting.

and 1 What I claim and desire to secure by Letters-Patent is: V 1. Aneye-glass mounting comprising a part to be secured t0 a lens, paralleljaw membersto receive the lens between them, tensioning means for thejaw members, and a cover plate carried by the tensioning means to coverthe outer jaw member; 2. An'eye-glass mounting comprising a part to besecured to a lens, parallel jaw members to receive the lens betweenthem, and tensioningmeans forthe jaw members comprising a removablelens-supporting, hollow, internally threaded stud carried by one jaw anda tensioning screwcarried by the other jaw and engaging the internallythreaded stud.

31 'An eye-glass mounting comprising a part" to be secured to a lens,parallel jaw members to receive the lens between them, an'dftensioningmeans for the jaw members consisting of a headed hollow, internallythreaded stud projectable through an opening in one jaw and a'headedscrew projecting through the other jaw and having threaded connectionwith the internally threaded stud. I

4. 'An eye-glass mounting comprising a part to be secured to a lens,parallel jaw members-- to receive the lens between'them,

8. An eye-glass mounting comprising a part to be secured to a lens,parallel jaw members carried by said part, one of which is provided withan outer face having inclined sides, a cover plate substantially V-shaped in cross section and lying co-exten- 10 sive with the jaw havingthe inclined sides so as to cover it, the engagement between the plateand the jaw bein such that there is no relative movement etween them, astud rigid with the. cover plate and projecting through itscomplementary jaw, and a tensioning screw projecting through the otherjaw and engaging the stud.
